(G1. sei-sr if t An object of my invention is to provide a base Figure a bottom planzviewof a bottom plate assembly for toasters or other electrical appliwhich is part of the assemblyf ances whicflA is simple in construction and which, Figure 5 is an enlarged bottom plan view/of .one .can be kassembled in a minimum periodfof time corner of the assembly before assembling is com- 5 without the use 'of screws or other fastenlng` pleted. a ,l v 5 .w means,v the ldevice lhowever being substantially :Figure Gils a. similar view showing the assembly durable and inexpensiv f t completed; and v r 1 A further object is to provide a. base assembly. l Figure 7 is anenlarged sectional view--onthez fortosters and the like comprising an invertedl 'line-T-'l 0f Figure-6- f .l .1 10 dishedbasejand 'a'bottom plate, ,these'twoparts y( )11-IIJ the, fcmvanyiug drawing; I ,have used 10 being so associated .was topermitair circulation tliereferen .character 1A to indicate generallya, under the `base and between the top of the baseI base memberand B a bottomlplate therefor.` The and the bottom plate to carry -heatgaway from base andwitsbottomtplateare adapted to support parts ofthetoaster or,other.appliancefmounted :any kndnpf all IBC1TCLaPP1QDQG, `Slmh fOr-rex;- on thebaef a' amplgsml935mg:@illustrated by ,d0tted`15 r`Still ja further object is to; assemblethe bottom lines in Figure.1.3TbebaSemember Aomprises y plate relative to the dished Vbaste in la permanent" ailat top lll'having giowrl-tllrxi ed` endlanges l2 manner' .w`ithout the use' of screws or other fase" and Side 1 al1gesl4l.y ,gltthecorners the flanges y teningfmeans and by comparatively `simple ai I r2:, and il4 have olfsegportionsfindicatedat |B, sembling operations. y which'I call shoulders:by Below the shoulders [M20 Another object is t'olprovide `a' ,basehavingpithe flanges I2 gand i-4 extend downwardly as irland the engagementolffthe bottomplate with the come; projectionsfzgsneped' to at inside the' 25 noted, support the lower edge of thebase member the edges of said bottom between said shoul- A above the surface to permit such circulation. The edges 24 and 26 of the bottom plate B are spaced inwardly from the flanges I2 and llto provide spaces indicated at 36 and 33 respectively in Figures 2,Y 4, 5 and 6. Figure 4 shows the inner surfaces of the flanges l2 and Il'as a dotted line in order to clearly illustrate the 'spaces 36 and 38. 'I'he spaces 36 and 33 permit air circulation as indicated by the arrow b in Figure 2.

The plate B is held assembled relative to the base member A in a unique manner without screws or other fastening means. This consists of depressions 40 pressed into the center part of each flange portion I8 after the part B is inserted into position against the shoulder I6. zIn Figure 5 I illustrate the plate B inserted in the base member against the shoulder i6 and in Figure 6 I show the next step in the assembly process, consisting of bending the depression 40 inwardly so that the plate B is then permanently assembled relative Ato the base member.

The plate B may be formed of comparatively thin metal and reinforced against bending and springing out of position relative to the base member A by ribs 42 formed therein crossing each other and terminating at the depressions 28 as shown in Figure 4.

The particular construction I have disclosed provides for an effective circulation of air both over the plate B and between it and thebase plate I0 to dissipate heat from the parts of the toaster or other electric apparatus projecting into the base and to also dissipate heat conducted through the base to the space therewithin.

Even though accomplishing these desirable re-4 sults the assembly is simple and readily assembled without having to use any parts in addition to the two parts A and B.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention and it is my intentionto cover by my claims any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:
